Mourinho has repeatedly applied pressure on Woodward to finalise transfers during his pre-season press conferences and admitted he would be 'happier' if United brought a fourth player in.

"Everybody's in the plan," Mourinho said after the win over Sampdoria in Dublin on Wednesday night.

"The plan is to have a good squad, not to have a good team, it's to have a good squad with options and we have important players injured for a long time, they are going to be back just by the end of the year, so our squad is not so big and we need options, we need different players.

"Lukaku, Martial and Rashford are all different players and we need everybody and it's going to be good, it's going to be fun to choose the team for every match, according to the plan, to the opponent, to our gameplan.

"So the squad is good and, as I told a few months ago, I was hoping for four players to improve the squad and the club did a fantastic job,absolutely fantastic, by getting three of them, which is difficult in the crazy market where we are now.
